Physics is the fundamental science that explores the laws governing matter, energy, and their interactions. Central concepts include force, motion, and energy, with forces described as vectors that influence the acceleration, velocity, and equilibrium of objects. Newton’s three laws of motion explain how objects respond to applied forces, while concepts like mass, weight, momentum, impulse, work, power, and energy quantify these interactions. Mechanical energy can exist as kinetic or potential...

Electric charge is a fundamental property of matter, existing in discrete positive and negative forms that interact through attractive and repulsive forces. Charges can be transferred by friction, contact, or induction, and their behavior depends on the material—conductors allow easy movement of charge, while insulators restrict it. Electric fields, created by source charges, exert forces on other charges and can be visualized using field lines, equipotential surfaces, and Gaussian surfaces. K...
